Motoman Robot Handling and IMM Tending

Motoman HP50 robot, equipped with multi-function gripper, unloads journals and link bars from a pallet on an infeed conveyor and unloads/loads molded parts from/to an IMM onto an outfeed conveyor.Automotive Powertrain Hardware

Robot system meets or exceeds project requirements for automated insertion and removal of parts from IMM operation. Cycle time is 12 seconds, which is well within the 14 seconds of time allowed for load/unload operations (15.7 percent faster than requirement). Robot system increased productivity and throughput, as 70-second closed and mold transition cycle was reduced to 65 seconds. Flexible system handles variety of required part sizes and manual changeover is 15 minutes or less. Sensor checks gripper details, and also indicates proper part type and link bar orientation.

Fixtures/Tooling Details

Motoman Robotics provided custom end-of-arm tooling consisting of a multi-function gripper with three sets of mechanical jaws. Two O.D. grippers pick up link bars and two I.D. grippers on extendable cylinders pick journals from the manually loaded pallet. Two additional O.D. grippers unload finished (molded) parts from the IMM to the exit conveyor. Changeover for each part requires relocation of the grippers for the proper part placing locations. Gripper presents link bars to a laser through-beam checking station that checks for correct gripper details, and then checks flipped link bar for proper part type and part orientation. Gripper includes sensors for open/closed and cylinder extended/ retracted conditions.
